Ok - let's make things short. Odoo is using Wkhtmltopdf dependency to print pdf files. If you installed Odoo and haven't installed Wkhtmltopdf then you won't be able to print pdf and your customers won't be able to finalise their transaction in some cases (they will get "Internal Server Error"). This tutorial will show you how to install and configure Wkhtmltopdf with Odoo 12 and Ubuntu Linux 18.04

If you just installed the latest version of Wkhtmltopdf, then you may have to repeat the process and install the correct one.
